Question

我希望能够定义列数，但是，这不会定义列。当您看到输出更改行数而不是列数时，您会注意到。

我已尽可能详细地记录，感谢您的帮助！如果我犯了错误，第一次张贴就这样对我说：）

public function SplitIntoColumns(array $arrayTranspose=array(), $no_of_cols=3,$min=0) {
    $result = '<div class="column">'."\n";
    // The 2D array
    $colArr = array();
    // The tmpArray
    $tmpArray = array();
    if (count($arrayTranspose) <= $min) {
        $result .= implode("\n", $arrayTranspose);
    }
    else {
        // Set size of the array    
        $cnt = intval(floor(count($arrayTranspose)));
        $row = 0;
        $col = 0;
        // Create Multidimensional array from Single dimensional array
        foreach($arrayTranspose as $key => $val){
            $colArr[$col][$row] = $arrayTranspose[$key];
            // Store the data from the array
            $result .= $colArr[$col][$row]." ";
            $col++;
            // If columns are equal to the set value then start
            // From the beginning on a new row
            if($col == $no_of_cols) {
                $col = 0;
                $row++;
                // create columns
                $result .= '</div><div class="column">'."\n";   
            }
        }
    }
    // This says numberOfRows, but it is actually the number of columns
    $numberOfRows = intval((floor($cnt) / $no_of_cols));
    // A loop to transpose into columns
    for($i = 0; $i <= $no_of_cols; $i++) {
        for($j = 0; $j <= $numberOfRows; $j++){
            $tmpArray[$j][$i] = $colArr[$i][$j];
            $result2 .= $tmpArray[$j][$i].' ';  
        }
        $result2 .= '</div><div class="column">'."\n";
    }
    // return stuff
    $result2 .= "</div> <!-- /.column -->\n";
    return $result2;
}
}
$Util = new SplitColumns();
$content = array('Lorem ipsum','elit sed do','labore et dolore', 'dolor sit amet', 'eiusmod tempor', 'magna aliqua',  'consectetur adipisicing', 'incididunt ut');
// This is where you can define the number of columns you want
// However, this does not define columns.  You will notice when
// You see the output that it changes the number of rows
echo $Util->SplitIntoColumns($content, 4);

此输出：

Lorem ipsum eiusmod tempor
elit sed do magna aliqua
labore et dolore consectetur adipisicing
dolor sit amet incididunt ut

所需的输出应为：

Lorem ipsum labore et dolore eiusmod tempor consectetur adipisicing
elit sed do dolor sit amet magna aliqua incididunt ut

你的事情太复杂了！使用array_chunk()结合一些简单的数学运算来正确格式化数据：

function splitIntoColumns($array, $columns=3)
{
    $numberOfRows = ceil(count($array) / $columns);
    return array_chunk($array, $numberOfRows);
}

这将为您提供一个列数组 - $ returnValue [0]是第0列中元素的数组，依此类推，直到列限制。示例输出（4个字符串）：

array(4) {
  [0]=>
  array(2) {
    [0]=>
    string(11) "Lorem ipsum"
    [1]=>
    string(11) "elit sed do"
  }
  [1]=>
  array(2) {
    [0]=>
    string(16) "labore et dolore"
    [1]=>
    string(14) "dolor sit amet"
  }
  [2]=>
  array(2) {
    [0]=>
    string(14) "eiusmod tempor"
    [1]=>
    string(12) "magna aliqua"
  }
  [3]=>
  array(2) {
    [0]=>
    string(23) "consectetur adipisicing"
    [1]=>
    string(13) "incididunt ut"
  }
}

从那里添加HTML应该相当简单，并且可以通过多种方式实现，例如：

$result = splitIntoColumns($inputArray, 3);

foreach($result as $column => $columnMembers)
{
    echo '<div class="column">';
    foreach($columnMembers as $key => $val)
    {
        echo $val; 
        //or whatever else you want to do in here
    }
    echo '</div> <!-- /column -->';
}

您可以更简单的方式获得预期的输出：

$content = array('Lorem ipsum','elit sed do','labore et dolore', 'dolor sit amet', 'eiusmod tempor', 'magna aliqua',  'consectetur adipisicing', 'incididunt ut');    
for($i = 0; $i<count($content); $i++){
    if($i % 2 == 0){
        $col1 .= $content[$i] . ' ';
    }
    else{
        $col2 .= $content[$i] . ' ';
    }
}    
echo $col1 . "\n" . $col2;

<强>输出：

Lorem ipsum labore et dolore eiusmod tempor consectetur adipisicing
elit sed do dolor sit amet magna aliqua incididunt ut

我想定义列数而不是行数
